Easy lives

Use the following trick to get 99 lives with two players. In World 4, enter the Supermassive Galaxy. You will eventually reach three turtles walking around in a circle. Take the Spin Drill and kill all but one of the turtles. Have the player two hold the last remaining turtle. Have player one run and jump on the turtle's back from behind it. Stay on the turtle. You do not have to do anything (such as pressing A as soon as you get on its back); Mario will jump anyway. Use the Wiimote to stay on its back so you do not jump off. You will get 99 lives from this, but they will not be saved after you turn off the game. This trick must be repeated to get the lives back.

Death counter

Collect the final star in The Grandmaster Galaxy (The Perfect Run) to see the number of deaths you have accumulated on your saved game file.

Skate backwards

Press Z while on ice.

Die during the credits

Collect a Bee Mushroom during the credits and wait for the Shiverburn area to start. When the page flips, fly toward the screen before you appear. If done correctly, you should die by falling. The screen will turn black while the sound effects from the credits play. At the end, it will read "THE END" with "TOO BAD" in the background.
